These two images were taken 75 minutes apart and show lightning storms on the night-side
of Jupiter along with clouds that are dimly lit by moonlight from lo, Jupiter's closest moon. Bright
storms can be seen at two latitudes in the left image, and at three latitudes in the right image.
Each storm was made visible by multiple lightning strikes during the exposure. The images show
that jovian and terrestrial lightning storms have similar flash rates, but that jovian lightning strikes
are several factors of ten brighter that those on the Earth. The images were taken on October 5th
and 6th, 1997, at a range of 6.6 million kilometers (4.1 million miles) by the Solid State Imaging
System on NASA's Galileo spacecraft.
